<p>DO THE HOMEWORK.</p>
<p>Every teacher does indeed grade differently, but there was only one class in my entire 4 years of high school where I never did the homework and still walked away with an A (Econ).</p>
<p>I agree with connecting with your teachers. I was good friends with all of my teachers, and it helps you especially when you’re right on the border. For instance, I helped a teacher out by working in his room for Open House while he was playing in an alumni volleyball game, and at the end of the semester when I was at an 89.8%, I mysteriously went up to a 90.0%. :)</p>
